DEVICE FOR FASTENING SPOKES TO RIMS OF WHEELS.

SPECIFICATION forming part of Letters Patent No. 646,306, dated March2'7, 1900.

. Application filed August 30, 1899. Serial No. 728,941. (No model.)

To all whom it may concern.-

Be it known that I, RICHARD MiiLLER, merchant, a subject of the King ofPrussia, Em-

peror of Germany,residing at Lemgo, St. Johannes Thor, (whosepost-otfice address is Lemgo,) in the Kingdom of Prussia and Empire ofGermany, have invented certain new and useful Improvements in a Devicefor Fastening the Spokes to the Rims of Cycle and other Wheels, of whichthe following is a full, clear, and exact description. 7

This invention relates to an improved device for fastening the spokes tothe rims of cycle and other wheels which diifers, essentially, from themeans heretofore employed for that purpose in that it renders itunnecessary to form screw-threads on the outer ends of the spokes, andin the event of a spoke breaking it can be replaced by any suitablepiece of wire.

The invention is specially valuable for the very broad wheels ofAmerican cycles, in

which the india-rubber tires are so cemented that the air-tube mustalways be torn in order to get the screwed end of an ordinary spoke intoplace.

The accompanying sheet of drawings illustrates the invent-ion applied tothe rim of a cycle-wheel.

Figure 1 is a longitudial sectional elevation,

and Fig. 2 a sectional elevation taken at right angles to Fig. 1.

a is a screwed stem which is passed through a hole in the outer wall ofa hollow rim 1) and has a cylindrical neck which fits and rotates insaid hole in the hollow rim and a broaden edout head which bears againstthe inside of the said rim, while the stem itself can be rotated in thehole in the rim by means of a key applied to the square part of the stema. c is a kind of stirrup piece forming a nut which is tapped with ascrew-thread to correspond to the screw-thread on the stem (1 and isprovided with a flattened part having a slot d formed therein. The endof the spoke eis bent and furnished with a rivet-head, as shown, and isthen hooked into the slot d. Then by turning the screwed stem a, whilethe part c is prevented from turning, the spoke e is tightened up as maybe required.

What I claim, and desire to secure by Letters Patent, is-

The combination of the hollow rim 6, the screw-stem at having a headretained within the coating of the hollow rim and bearing against theouter wall thereof, a cylindrical neck fitting and rotating in anaperture in said outerwall of the hollow rim, an external square for thereception of a turning-key, and ascrew-threaded extremity; thestirrup-piece 0 having an internal screw-thread to receive the threadedextremity of the stem and a slot RICHARD MULLER. \Vitnesses:
